PacketTrends vs Kerchunk

PacketTrends keeps an eye on the hosts and services you care about and alerts you the moment something breaks. Connect the app to your PacketTrends workspace to see your whole fleet at a glance — every monitored host, colour-coded by health, with latency and packet loss right there. • ICMP ping checks — reachability, round-trip latency, jitter, and packet loss • TCP port checks — handshake success, time-to-connect, and timeout/refused rates for any port (443, 22, 8089, and more) • One host, many checks — track a server's ping plus several ports independently • Per-host history — latency and connect-time trends over minutes, hours, and days • Push alerts — get notified instantly when a host goes down, and again when it recovers • Manage on the go — add, edit, and remove hosts and toggle alerts from your phone No account? Tap "Explore the demo" on the first screen to browse a live sample workspace — no sign-up required. PacketTrends is a companion app for an existing PacketTrends monitoring account.

Kerchunk is a repeater directory for amateur radio operators. Find the repeaters around you on a map, see everything you need to work them, and plan which ones you'll pass on a drive — with the whole directory kept on your phone so it works where there's no signal. Buy it once. No subscription. MAP • Every repeater around you, drawn where it actually is • Filter by band and mode: FM, DMR, D-STAR, Fusion, NXDN • Tap any repeater for the full details • Sort by distance, so the nearest is the first thing you see WHAT YOU NEED TO WORK IT • Output and input frequency, and the offset • Uplink and downlink tones, so you can set both squelch and access • Modes, band, access type and operational status • Location, grid square, city, county and state TRIP PLANNER • Set a start, an end and any stops in between • See the repeaters along your route, not just the ones near its ends • Pick the ones you want and keep them with the trip • Save trips and edit them later OFFLINE • The directory lives on your phone, not just in the cloud • Search and map work with no signal — which is when you need a repeater most • Syncs changes when you're back online KEEP IT ACCURATE • Submit a repeater that's missing • Correct one that's wrong • Confirm the ones you've actually worked, so other operators know the entry is current Kerchunk reads the OpenAPRS repeater directory, and everything you contribute goes back into it.
